Two people were transported to hospitals for inhalation injuries, others were treated at the site of a reported chlorine leak in Marshall County. Communities in the area were evacuated. Officials from Axiall Corporation say a rail tanker car loaded with liquid chlorine developed a leak Saturday morning inside the company's facility near Proctor, W.Va.

By early Saturday evening when air monitoring indicated the gas had dissipated, company officials gave local authorities the "all clear." Community members could return home, and traffic in and along the river could resume. Work to transfer the remaining chlorine to another rail car continues at the Natrium plant - formerly owned by PPG and now by Atlanta-based Axiall.

Many questions remain unanswered about the event. The West Virginia Department of Environmental Protection is working with company crews and the Environmental Protection Agency to investigate how the accident occurred. How much chlorine was released and over what period of time is still unreported. Community members are also asking why a warning siren didn't sound.
